void (): drakboot "INTERNAL ERROR: unknown device"

Wednesday, January 16, 2019

1: obviously, run strace drakboot > /tmp/trace 2>&1

2: less /tmp/trace, look for the missing device (in my case it was sdd):

openat(AT_FDCWD, "/boot/grub2/install.sh", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = 12

ioctl(12, TCGETS, 0xbfb7147c) = -1 ENOTTY (Inappropriate ioctl for device)

_llseek(12, 0, [0], SEEK_CUR) = 0

fstat64(12, {st_mode=S_IFREG|0755, st_size=22, ...}) = 0

read(12, "grub2-install /dev/sdd", 8192) = 22

read(12, "", 8192) = 0

3: edit /boot/grub2/install.sh and replace the wrong disk reference.
